Space heaters are preferred over hot air ducts. In
homes with forced air heat, use filters or damp cheesecloth over inlets to
reduce dust circulation. Change every two weeks. Consult your physician about
air purifiers. Keep beds away from air vents.

Install central air conditioning or window units.
Keep windows closed, especially during periods of high pollen counts and windy
conditions. Grasses, weeds, and trees tend to pollinate during the early morning
hours. Sleep with the windows closed.

When choosing furnishings, it is best to go with
wood, leather, vinyl, or rubberized canvas furniture and avoid upholstered
pieces. Upholstery easily traps allergens and is much harder to clean. You might
try washable slipcovers on existing upholstered furniture.
